The Fortran calling convention is defined in OPTS, FOPTS, and NVOPTS using -DADD_ or -DNOCHANGE or -DUPCASE.
I don't understand why you are seeing this error as you have -DADD_ in OPTS.

Is this happening when you compile MAGMA code or when you compile your own code?

Can you copy-and-paste the whole output of make when this occurs? That is, include the command that is generating the error, not just the error itself. Otherwise it's very hard to tell what is happening.

Yes, I recognize the error and where in the code it is coming from, I just don't know why it is occurring. Can you include the compiler command itself, not (just) its output. For instance, on my machine:

As you can see there, it has -DADD_, which is the Fortran convention on my machine (and probably the most common convention). What I don't understand, and can't tell without seeing your actual compiler command, is why that is missing. According to your first message, the OPTS had -DADD_ in it, in your make.inc file.

I'm using code:block 10.05 in order to compile testing_dgesvd.c
Yes, the make.inc file has PTS with -DADD_ .
Do you think is it not enought? Should have I to specify the fortran convention ADD_ also in the code:block enviroment?

Are the *.co files where it thinks they are, in /home/gabriele/clmagma-1.0.0/interface_opencl ?
If they are somewhere else, you need to set the MAGMA_CL_DIR environment variable, as mentioned in the README.
If they were not created when clMAGMA was compiled, that is a different problem.
